Abstract (en)
[origin: EP1593693A1] This invention relates to a natural rubber improving the low heat buildup while maintaining the resistance to thermal aging inherent to the natural rubber as well as a rubber composition, and particularly to a natural rubber being a rubber made from a latex by partly removing protein from a natural rubber latex through a mechanical separation means in which a total nitrogen content in the rubber is more than 0.1% by mass but not more than 0.4% by mass, and a rubber composition comprising the natural rubber and a filler.
